Sun position tracking method for photovoltaic power generation

Abstract

The invention provides a sun position tracking method for photovoltaic power generation, and relates to the technical field of solar power generation, and the method specifically comprises the following steps: S1, device installation: enabling a solar photovoltaic panel for photovoltaic power generation to to be fixedly installed, enabling the solar photovoltaic panel to absorb solar energy, arranging a stand column in the middle of the top end of the solar photovoltaic panel, arranging a disc-shaped photosensitive bottom plate at the bottom end of the stand column, and arranging a plurality of photosensitive elements on the surface of the photosensitive bottom plate at equal intervals. The disc-shaped rotating disc is arranged at the bottom end of the solar photovoltaic panel, and the elevation angle of the solar photovoltaic panel at the top end of the chassis is adjusted, so the solar photovoltaic panel at the top end of the chassis rises towards the sun and follows the sun to the falling position, and the solar photovoltaic panel is always directly irradiated by the sun in the daytime, thereby further improving the power generation efficiency of the solar photovoltaic panel.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a sun position tracking method for photovoltaic power generation. Background technique [0002] Solar panels mainly convert solar radiation energy into electrical energy directly or indirectly through photoelectric effect or photochemical effect by absorbing sunlight. That is to say, the more solar radiation the solar panel receives, the more electricity it can convert, so the output power of the solar module depends on factors such as solar irradiance. Currently, since the solar panel is fixedly installed, the sun moves above the solar panel. Since the sun moves to the side of the solar panel during the movement, the sun moving on the side of the solar panel It will irradiate on the solar panel obliquely, and the oblique irradiation will easily reduce the absorption of sunlight by the solar panel and affect the conversion of electrical energy.

Problems solved by technology

[0007] Aiming at the problems in the prior art, the purpose of the present invention is to provide a sun position tracking method for photovoltaic power generation, which solves the problem that after the solar panel follows the sun and moves to the west, the solar panel stays in the direction where the sun falls , and when the sun just rises the next morning, because the solar panel is facing the direction of the sun falling, and the back of the solar panel is facing the direction of the sun rising, it will block a part of the photosensitive device on the surface of the solar panel, resulting in When the sun just rises the next day, the solar panels cannot accurately track to the direction of the sun, which affects the solar panel's ability to absorb sunlight all day long.
